3 Menus
The MENUs consists of nine parts: [INPUT/FILTERS], [REF/PHASE], [GAIN/TC], [DISPLAY], [SAVE/LOAD],
[CHANNEL OUTPUT], [SAMPLE], [AUTO SET] and [SYSTEM], see the front panel of SE1022D in Fig 9. Each
button has an independent corresponding submenu. In each submenu, use soft keys such as[CH A/B SWITCH],
[START CONT], [PAUSE CLEAR], [CURSOR], [ACTIVE CHART] to set parameters.
3.1 [INPUT/FILTERS]
When press the [INPUT/FILTERS] button, you will enter this following submenu, as is shown in Fig.13. There are
5 function settings in this submenu, including <Source>, <Current Gain>, <Grounding>, <Coupling> and <Line
Notches>. Soft key [CH A/B SWITCH] is provided for switching between two channels. Users can also switch
between two channels through knob.

3.1.1 <Source>: Setting the Input Signal Mode
<A>
Single-ended voltage input mode. Receive Signal from IN+ terminal.
<A-B>
Differential voltage input mode. Input Signals through IN+ and IN- terminals.
<I>
Current input mode. Receive current signal from IN+ terminal.
Note that when choose mode <A> and mode <A-B>, the amplitude of the input signal must be less than 1Vrms. In
mode <I>, the input current must be less than 1uA
3.1.2 < Current Gain >: Setting the Current Gain
<1M>
The input current is amplified by the gain of 10
6
V/A.
<100M> The input current is amplified by the gain of 10
8
V/A.
3.1.3 < Grounding >: Setting the Ground Mode
